METHOD OF FLOORING, BEDDING AND FLOOR MATERIAL TO BE USED WITH THE METHOD

Abstract: The invention refers to a method of floor laying and underlay and surface material for this. According to the invention a coating of fibre flock on the underlay as well as on the underside of the floor surface material is utilized. Hereby is achieved partly that the need of glueing of floor material is eliminated and partly to provide a floor underlay that gives smoothing out, noise suppression and insulation as well as a fixing underlay for various floor materials so that these can be laid in larger or smaller portions and remain on site but simply can be adjusted when required.

Description: Method of flooring, bedding and floor material to be used with the method. State of the art: At floor laying glue is frequently used to fix floor mats to the underlay, which constitutes a health problem in connection with the floor laying and a period of time thereafter, and causes much work in connection with re¬ laying of mats, since the glue frequently remains with portions of the floor mat or conveys portions of the floor underlay at the removal of the mat. For instance when laminate floors are layed frequently an underlay in the form of grey-rag-board or a board with cork scraps or a thin cellular plastic material is used in order to even roughness in the underlay and give a less rigid underlay which gives some elasticity, sound damping and insulation. Technical Problem: The problem that is solved by the present invention is to eliminate the need of glueing floor material and to provide a floor underlay that gives smoothing out, noise suppression and insulation as well as a fixing underlay for various floor materials so that these can be laid in larger or smaller portions and remain on site but simply can be adjusted when required or being exchanged. Prior Art: In connection with gymnastics mats and the like, separated into several smaller sections, fibre flock has been used on the undersides of the mats and on an underlay in order to make the mats to remain on site during exercises and at intervals be able to be removed, which is evident from DE Al 24 27 712. However, in this document nothing is disclosed that gives an indication about using corresponding method to eliminate glueing in connection with a durable laying of floor material of hard or semi-solid type in order to form a regular flooring. The Solution: According to the present invention one has therefore provided the floor underlay wholly or partly with fibre flock on the surface facing upwards. The surface material of the floor in a corresponding way is provided with fibre flock on the underside. According to the invention these materials are utilized at the floor laying, whereby the above stated problem is solved. The floor underlay may be constituted by the existing underlay in the form of fibre boards, boards, concrete floor or other which after necessary levelling is directly coated by an adhesive in which the fibers are applied by some known method which makes the majority of the fibers to be fastened in the main perpendicularly from the underlay, for instance by means of an electrostatic method. Such a coating can also be provided on a previous flooring to be covered. Alternatively, a foil, board or slabs which wholly or partly has been coated with fibre flock, is put on the floor underlay whereby the surface provided with the fibre flock is put upwards . The support material thus produced in this manner can be provided on rolls or as slabs. The surface material can be constituted by practically all available floor materials, such as plastic and linoleum mats, laminates and ceramic material. Since the underside of the surface material has been coated with fibre flock this will attach to the fibers of the underlay and the surface material will remain on site without need of glueing. Even one or several of the edge surfaces of the surface material may be coated with fibre flock, whereby for instance ceramic slabs, wood or laminate may obtain fixation to each other not only along the plane of the underlay but also in a vertical plane. The fibre flock thereby can complete or wholly replace joining by glue and other materials for joints. The sides coated with fibre flock of the underlay as well as the surface material can be coated in its entirety. It is also possible that either or both only partially is coated by fibre flock without deteriorating the function according to the present invention. The method to cover a surface with fibre flock is well known. A common method resides in that a surface first is coated with an adhesive whereafter electrically charged fibers may land in the adhesive and stick there. The adhesive is frequently a two component resin glue and the fibers are generally synthetic fibres of for instance polyamide. The fibers which may be considered for the present invention are however not limited to some special type, but even for instance carbon fibres, glass fibre or the like may be considered. There are also other methods to cover a surface with fibre flock without use of electrically charged fibers which can be utilized in connection with the present invention. In a preferred embodiment of the present invention a large amount of fibers is utilized which at electrostatic application to a major part will be attached perpendicularly against the underlay. The fibre density can amount to 50-300 fibers per square mm, preferably more than 150 fibers per square mm, with a fibre thickness less than 0,1 mm, preferably less than 0,05 mm and a length amounting to 0,5-5 mm, preferably less than 3 mm. The invention is not limited to the embodiments mentioned above but can be varied in different ways within the scope of the patent claims.

Claims: CLAIMS 1. A method of permanent coating of an underlay with a wearing surface material on floor surfaces and the like, characterized therein that the underlay at least partly is provided with fibre flock or an underlay material which on the top at least partly is covered by fibre flock and that a floor surface material which on the underside at least partly is covered by fibre flock is put directly on the underlay material. 2. A method according to claim 1, characterized therein that the fibre flock is constituted by synthetic fibers which by an electrostatic application method or by another method is applied in an adhesive directly on the floor underlay or on the underlay material and on the floor material. 3. An underlay material of a floor, intended to be placed between a floor and the surface layer of the floor, characterized therein that it is constituted by a sheet or plate shaped support onto which fibre flock has partly been applied at least on one side of the support. 4. An underlay material according to claim 3, charac- terized therein that the support is constituted by a plastic material, paper or the like. 5.
